Willy,
What version are you planing on building?
I ask because I don't think the T-38 ever had wingtip sidewinder rails.
The 2 seat F-5 did but that has leading edge slats. The T-38 did not have them.
The T-38A has a centerline hard point for a luggage container.
I think the T-38B had a centerline hardpoint. I don't believe any T-38s ever had
wing hard points, but I could be wrong.
In any event I like the build so far!
